Definitions

  • the present invention relates to obtaining agglomerates of faujasites with a low silicon / aluminum ratio and a low content of inert binder.
  • zeolites The synthesis of most zeolites is mainly carried out by nucleation and crystallization of silicoaluminate gels, the result of which is zeolite in very small crystals.
  • powders these powders are of an awkward industrial use and we prefer an agglomerated form granular.
  • agglomerates whether in the form of platelets, beads or extrudates, commonly consist of a zeolite powder, which constitutes the active element and a binder intended to ensure the cohesion of the crystals under grain form.
  • This binder has no adsorbent properties, its function being give the grain sufficient mechanical strength to withstand vibrations and movements to which it is subjected during its various jobs.
  • These granules are produced by pasting the zeolite powder with a clay paste, in proportions of the order of 80% powder for 20% of binder, then shaped into beads, wafers or extrusions, and high temperature heat treatment for clay firing and reactivation of the zeolite.
  • zeolitic bodies with a particle size of a few millimeters, and which, if the choice of the binder and the granulation are made in the rules of the art, have a set of satisfactory properties, in particular porosity, mechanical strength, abrasion resistance.
  • the application properties are obviously reduced in the powder ratio active with powder and its inert agglomeration binder.
  • the zeolitization of the binder occurs during step d), by action of the caustic solution which must be at least 0.5 molar, and which can be a soda and potash solution in which the potash is present at a maximum content of 30 mol% (relative to the soda + potash set). he may be advantageous to use a soda solution. We do a sufficient temperature to obtain a reasonable zeolitization speed.
  • Zeolite clay belongs to the family of kaolinite, halloysite, nacrite or dickite. We use kaolin very simply.
  • X-ray diffraction analysis confirms that the powder formed consists of practically pure faujasite, accompanied by traces of zeolite A, the content of which is estimated at less than 2%.
  • a measure of capacity adsorption of toluene is carried out, after calcination at 550 ° C. for 2 hours, under an inert atmosphere: there is an adsorbed capacity of 22.5% at 25 ° C and under a partial pressure of 0.5.
  • Part of the powder is shaped by mixing 42.5 grams (expressed in calcined equivalent), 7.5 grams of a clay fibrous (expressed in calcined equivalent), 1 gram of carboxymethylcellulose and adequate water to be able to extrude in the form of extrudates 1.6 mm in diameter and about 4 mm long.
  • the extrudates are brought to dry at 80 ° C and are then calcined at 550 ° C for 2 hours under inert atmosphere.
  • the LSX zeolite powder of Example 1 is used with agglomeration, with a mixture of a montmorillonite-type clay (15%), a clay of kaolin type (85%), a little carboxymethylcellulose and water. extrusion completed, drying is carried out at 80 ° C and caicination at 600 ° C for 2 hours, under an inert atmosphere free of water vapor.
  • a solution containing 16.7 grams of sodium hydroxide is prepared. lozenges, 7.7 grams of potash (expressed as pure), in 100 ml of water. We immerse 10 grams of freshly calcined zeolite grains in 17 ml of this solution and the whole is brought to 95 ° C., without stirring.
  • Solid samples are taken after 3, 6 and 24 hours, in order to to follow the evolution of crystallinity as a function of time. Each of these samples are washed by immersion in water at a rate of 20 ml / g; 4 washes are carried out.
  • Toluene adsorption capacity measurements are carried out under the conditions described above and the following values are found: Agglomerated LSX (untreated NaOH + KOH) 18.2% Agglomerated LSX (NaOH + KOH treated, 3h reaction) 21.7% Agglomerated LSX (NaOH + KOH treated, 6 hr reaction) 21.6% Agglomerated LSX (NaOH + KOH treated, 24 h reaction) 21.6%
  • the X-ray diagrams essentially show the presence of faujasite, with some traces of zeolite A in an amount similar to what was measured on the powder before agglomeration. Chemical analysis leads to a overall Si / Al ratio of 1.04, corresponding to the objective sought.
  • the report Si / Al measured by R.M.N. of silicon is equal to 1.01 and corresponds to the ratio of crystal lattice.
  • the LSX zeolite powder of Example 1 is used with agglomeration, with a mixture of a montmorillonite-type clay (15%), a clay of kaolin type (85%), a little carboxymethylcellulose and water. extrusion completed, drying is carried out at 80 ° C and calcination at 600 ° C for 2 hours, under an inert atmosphere free of water vapor.
  • Toluene adsorption capacity measurements are carried out under the conditions described above and the following values are found: Agglomerated LSX (not treated) 18.2% Agglomerated LSX (NaOH treated) 22.4%
